Abstract
The invention discloses a diatomite papermaking wastewater treatment agent and a preparation method. The treatment agent is prepared from, by weight, 50-70 parts of roasted diatomite powder, 10-30 parts of original diatomite powder and 10-20 parts of flocculant powder. The preparation method includes the steps that 1, exploited original diatomite is added in a rotary kiln to be roasted and smashed into fine powder; 2, the exploited original diatomite is dried and smashed into fine powder; 3, the roasted diatomite powder, the original diatomite powder and the flocculant powder are added in a stirrer to be stirred and mixed evenly. The diatomite papermaking wastewater treatment agent and the preparation method have the advantages that the purification performance is good, the treatment cycle is short, no temperature requirement or foul smell exists, treatment materials are easy to obtain, the human input for operation and management is small, and the treatment cost is low.
Description
Technical field
The invention belongs to environmental protection technical field, be specifically related to Wastewater treatment agent for paper mill.
Technical background
In the past, Sewage many employings biochemical process, generally first made sewage ferment, then added anerobe and decompose, digestion nuisance.Biochemical process is disposed of sewage, and has requirement (can not lower than bacterial activity temperature), long processing period (usual more than 5 days) to sewage disposal temperature, and smell is large, pollutes ambient air, is subject to related factor, causes sewage disposal not up to standard.Operate, manage and protect human input amount greatly, processing cost is high.
Summary of the invention
The object of this invention is to provide a kind of diatomite treating agent for papermaking wastewater and preparation method, for the dirty water purification of papermaking discharge, overcome papermaking wastewater above shortcomings in prior art.
Treatment agent of the present invention is powders mixture, and its composition comprises: calcined diatomite powder, diatomite original soil powder, flocculation agent.
Treatment agent raw material dosage parts by weight ratio of the present invention is: calcined diatomite powder 50-70 weight part, diatomite original soil powder 10-30 weight part, flocculation agent powder 10-20 weight part.
Treatment agent raw material preferable amount of the present invention is: calcined diatomite powder 60 weight part, diatomite original soil powder 25 weight part, flocculation agent powder 15 weight part.
Flocculation agent is wherein the normally used product of Water warfare in the past, as flocculation agents such as polymerize aluminum chloride, poly-ferric chloride, polyacrylamide negatively charged ion.
Preparation method of the present invention is:
1, diatomite original soil is added in rotary kiln, under 400-1200 DEG C of temperature condition, fire 20-40 minute, after kiln discharge, be ground into 80-300 order fine powder;
2, the diatomite original soil exploited out is broken into 80-300 order fine powder;
3, calcined diatomite powder, diatomite original soil powder, flocculation agent are added stirrer and be uniformly mixed, obtain diatomite treating agent for papermaking wastewater.
The using method of sewage-treating agent of the present invention is:
Treatment agent powder is added in papermaking wastewater in what set with the ratio of papermaking wastewater, first in air flotation pool, carries out air supporting process, inject settling bowl afterwards, after sedimentation, emission standard water purification must be met.
Positively effect of the present invention is: adopt the diatomite with good adsorbent function to be main component, is aided with the flocculation agent composition treating agent for papermaking wastewater of suspended solid, can in the very short time by sewage purification to can emission standard, the water conditioning of discharge.Certain paper mill is actual use in the data that obtain of side be: treatment agent is thrown in papermaking wastewater by the ratio adding 1-1.5kg treatment agent with every 1m3 papermaking wastewater, in air flotation pool air supporting 10-15 minute, proceed to sedimentation 20-30 minute in settling bowl again.Front and back can complete the process to sewage less than one hour, and treatment cycle shortens greatly.And treating processes is without temperature requirement, odorless.Process material is easy to get, and operate, to manage and protect human input few, processing cost is low.
